Novel mechanism of bacteriocin secretion and immunity carried out by lactococcal multidrug resistance proteins
(Amer Soc Biochemistry Molecular Biology Inc, Bethesda, 2003)
A natural isolate of Lactococcus lactis was shown to produce two narrow spectrum class II bacteriocins, designated LsbA and LsbB. The cognate genes are located on a 5.6-kb plasmid within a gene cluster specifying LmrB, an ...
Identification of quorum-sensing-regulated genes of Burkholderia cepacia
(Amer Soc Microbiology, Washington, 2003)
Quorum sensing is a regulatory mechanism (operating in response to cell density) which in gram-negative bacteria usually involves the production of N-acyl homoserine lactones (HSL). Quorum sensing in Burkholderia cepacia ...
Role of GacA, LasI, RhlI, ppk, PsrA, vfr and ClpXP in the regulation of the stationary-phase sigma factor rpoS/RpoS in Pseudomonas
(Springer-Verlag, New York, 2003)
RpoS is the stationary phase sigma factor responsible for increased transcription of a set of genes when bacterial cells enter stationary phase and under stress conditions. In Escherichia coli, RpoS expression is modulated ...
Auto immune thyroid disease: The pathogenesis of Graves disease and Hashimoto thyroiditis / Auto imunska bolest štitaste žlezde - patogeneza Graves-ove bolesti i Hashimoto tireoiditisa
(Univerzitet u Kragujevcu - Fakultet medicinskih nauka, Kragujevac, 2003)
It is generally accepted that autoimmune thyroid disorders, Graves disease and Hashimoto thyroiditis, differ in pathogenesis and clinical implications. In Graves disease the basic pathogenetic mechanism is B lymphocyte ...
Extrahepatic and intrahepatic veins of the portal system in the ground squirrel (Citellus citellus) / Ekstrahepatične i intrahepatične vene portalnog krvotoka jetre u tekunice (Citellus citellus)
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2003)
From studies of the extrahepatic veins and intrahepatic veins of the portal system in the ground squirrel, using anatomical methods and rentgenography the following can be concluded: The portal vein is formed by the ...
Stress applied during primary immunization affects the secondary humoral immune response in the rat: Involvement of opioid peptides
(Taylor & Francis Ltd, Abingdon, 2003)
The effect of unpredictable, inescapable and uncontrollable electric tail shocks (ES) on the humoral immune response to bovine serum albumin (BSA) was investigated in the rat. Contributions of the procedures that accompany ...
Autoimmune thyroid diseases: In vitro diagnostics / Autoimunske bolesti štitaste žlezde - in vitro dijagnostika
(Univerzitet u Kragujevcu - Fakultet medicinskih nauka, Kragujevac, 2003)
In diagnostics of autoimmune thyroid diseases a number of in vitro methods is used to evaluate thyroid function or examine the presence of an tithyroid antibodies which may be included in pathogenesis of the disease or ...
Effects of beta-adrenoceptor blockade on the phenotypic characteristics of thymocytes and peripheral blood lymphocytes
(Taylor & Francis Ltd, Abingdon, 2003)
The study revealed that beta-adrenoceptor blockade with propranolol (0.40 mg/100 g/day, s.c.) in adult male DA rats: (i) increased the thymocyte proliferation and apoptosis, (ii) caused disturbances in kinetics of T cell ...
Thymopoiesis following chronic blockade of beta-adrenoceptors
(Taylor & Francis Ltd, Abingdon, 2003)
The present study was undertaken in order to further clarify putative role of the adrenergic innervation in the regulation of the intrathymic T-cell maturation. For this purpose adult male DA rats were subjected to either ...
Correlation between age-related changes in open field behavior and plaque forming cell response in DA female rats
(Taylor & Francis Ltd, Abingdon, 2003)
We investigated the relationship between immunological and behavioral changes during ageing in Dark Agouti female rats. Results showed that ageing was associated with decreased exploratory behavior and increased emotionality ...
